Heat stress poses a substantial challenge to poultry production worldwide, highlighting the urgent need for effective management strategies. This study investigated efficacy of probiotics ( Saccharomyces cerevisiae ) and ascorbic acid as antistress agents using cloacal body surface temperatures (CT BST) heat biomarkers in broiler chickens. A total 56 chicks were used experiment divided into four distinct groups: control, (1 g/kg feed), (200 mg/kg feed) combination 200 feed, respectively). The lasted 35 days; measurements taken ambient temperature (AT), CT, BST. pens consistently exceeded thermoneutral zone (TNZ) established CT values chickens probiotic group significantly lower p < 0.05) compared control group. Additionally, BST + groups than those findings suggest that incorporating probiotics, with or without acid, can effectively reduce thereby, enhancing thermoregulation when implies diets may enhance health growth performance, potentially leading better feed efficiency reduced reliance on antibiotics. Implementing these dietary strategies could improve productivity welfare commercial settings.

Reducing the detrimental effects of heat stress (HS) in poultry is essential to minimize production losses. The present study evaluates dietary polyphenols prepared from underutilized wood byproducts on growth, gut health, and cecal microbiota broilers subjected acute (AHS). One hundred eight one-day-old Indian River were fed with 0%, 0.5%, or 1% shredded, steam-exploded pine particles (PSPP) their diet. On 37th day, forty birds equally distributed among four groups containing either a control diet at thermoneutral temperatures (NT0%) AHS 0% (AHS0%), 0.5% (AHS0.5%), (AHS1%) PSPP-supplemented diets. temperature NT room was maintained 21.0 °C, while, room, it increased 31 °C. negatively influenced performance parameters rectal (RT) broilers. AHS0% group showed higher expression NOX4, HSP-70, HSP-90 genes, while lower birds. In jejunum, mRNA SOD all under compared NT.

Concludingly, influences parameters, RT, stress, gut-health-related pathogenic penetration, but PSPP supplementation reduces its bad impact by overcoming increasing favorable bacterial abundance reducing penetration

This study investigated the effect of neonatal α-ketoglutaric acid (AKG) gavage feeding on broilers. The first experiment was conducted to determine AKG day-old A total seventy-two-day-old Ross 308 broiler chicks were divided into four treatment groups: (i) Two groups with 0.6 mL distilled water (DDW) for consecutive days (CON); (ii) fed 0.1% dissolved in DDW day hatch (AL) followed by 0.2%, 0.3%, and 0.4% three days; (iii) 0.2% (AH) 0.4%, 0.6%, 0.8% days.

Abstract In modern animal husbandry, stress can be viewed as an automatic response triggered by exposure to adverse environmental conditions. This range from mild discomfort severe consequences, including mortality. The poultry industry, which significantly contributes human nutrition, is not exempt this issue. Although genetic selection has been employed for several decades enhance production output, it also resulted in poor resilience. Stress manifested through a series of physiological reactions, such the identification stressful stimulus, activation sympathetic nervous system and adrenal medulla, subsequent hormonal cascades. While brief periods tolerated, prolonged have more consequences. For instance, extreme fluctuations temperature lead accumulation reactive oxygen species, impairment reproductive performance, reduced immunity. addition, excessive noise slaughterhouses linked altered bird behaviour decreased efficiency. Mechanical vibrations shown negatively impact meat quality broilers during transport well egg hatchability hatcheries. Lastly, heavily influenced light intensity regimens, inadequate management result deficiencies, visual anomalies, skeletal deformities, circulatory problems. there growing body evidence demonstrating stressors on physiology, disproportionate representation research. Recent studies focused chronic heat stress, reflecting current interest scientific community climate change. Therefore, review aims highlight major abiotic elucidate their underlying mechanisms, addressing need comprehensive understanding diverse contexts.
